BUTTE-R CUTTER.

Application filed June so, 1928. seriai no. 289,409.

My invention relates to a new and useful improvementin a buttercutter'andhas for 7 its object the provision of a device whereby acakeof butter may be cut into a -plurality of small cakes for individualSGTVICQ.

It is another object of the inyent on to provide a device of this classwhich is simple in structure,-economical of manufacture and highlyetlicient in use. I

Another object of the invent on is to provide a buttercutter of thisclass hav ng a plurality of cutting wires, each ndividual andseparatefrom the other and removable and replaceable thereinindependently. 7

Another object of the invention is the provision of a butter cutter ofthis class hav ng a plurality ofseparate, independent cutt ng wires, andmeans for locking said cutt ng wires on a retaining frame and stretchingsaid wires'to taut condition. y I

Other objects will appear hereinafter.

The invention consists in the combination and arrangement of partshereinafter described and claimed. v v

The invention will be best'understood by a reference to the accompanyingdrawings which forma part of this specification and in which, I

The device comprises a frame. having on positely disposed endrails 15and 16, each provided with a lug 15 and 16 respectively, having anopening formed therein, these lugs affording handholds for holding thedevice when it is being used. The end rails 15 and are connected by andpreferably formed integral with side jrails 17 and 18 which areoppositely disposed. Projecting laterally outwardly from the uppersurface ofeacli of the side rails 17 and 18 are flangesl? and 18respectively, these flanges overlying an extension orboss 19 whichprojects outwardly from the lower surface of the end rails 15 and 16 sothat a space 20 is provided between each of the bosses and the flanges17 and 18 at the ends thereof. PIVOiTQllylIlOllIltQdLflt' one endbetween one of the bosses 19 and one end of the flange 17 or 18,as thecase maybe, is a locking bar 21. Threaded into the bosses 19 at opposite sides is a screw 22 provided with an I extension 23 of reduceddiameter adapted, upon swinging of the locking bar21 to closed oroperative position, for engaging in an opening 24 formed in thislockingbar adacent its free end. A collar 25 is'formed on the s ciew 22, andprojected "into the end rail 15 is a pin 26 adapted to engage thiscollar 25 upon unthreading of the screw 22 a predetermined distance, sothat the removal of the screw therefromisprevented, while unthreading ofthe screw sufficiently to dis- "engage the extension 28 from the opening24.- is perm tted. 1

The flanges 17 and 18' are provided with a'plurality of spaced notches27, the respective notches in the flanges 17 and18"- being lIl'alignment WVltll each other. cutting element formed from wire andcomprising the main body 28 is provided, the end of this cuttingelementbeing doubled upon itself to provide the inwardly projecting portion 29at each end, this inwardly projecting portion being doubled upon itselftoprovidea U-shaped structure 30. When the. cutting" element28 isp'lacedin position," the portion 31 of the cutting element will liev inone of the slots 27, as clearly appears in Fig. 2, the portion 29extending inwardly in engagement with the undersurface of the flange 17or 18'. After the cutting elementhas been placed in position, thelocking bar will be swung to closed position shown in Fig. 2, thislocking bar engaging in the U-shaped portion formed on the end of thecutting element and serving to press the cutting element inwardly of theflange at its ends, so as to stretch it taut across the frame, and thuscausing it to extend in taut cOIldition 83 and 34: extended across atright angles to each other. This frame is provided with the lugs 35 and36.

The butter operated upon by such a cutter is generally formed in a brickand this brick is usually quartered by the quartering device, which isaccomplished by pressing the frame 32 over the brick, the frame 32 beingof a size to snugly fit the brick. After the quartering of the brick theframe carrying the cutting elements 28 is pressed downwardly over thebrick, thus dividing the quartered sections of the brick into smallpieces.

In Figs. 7 and 8 I have shown a modified form of securing means wherebythe locking bar 21 may be locked in position. To this end I provide inthe flanges 1.7 and 18 a notch 37. A locking bar is bifurcated at itsfree end 38 and pivoted between the prongs is a link 39 which, when thelocking bar 21 is moved to closed position, may be swung into verticalposition, as shown in Fig. 8, so as to engage in the notch 87, and thussecurely lock the locking-bar in operative or locking position. 7 y

In Figs. 9 and 10 I have shown a further modified form of securing meanswhereby the locking bar 21 may be locked in position. In this case Ihave pivotally mounted a yoke l1 on the locking bar 21 adapted to swingaround in embracing relation'on a boss 40 projected outwardly from theend rail. A set screw 42 serves to lock this yoke in position to retainthe locking bar 21 in operative position.

Vhile I have illustrated and described the preferred form of myinvention, I do not wish to limit myself to the precise details ofstructure shown, but desire to avail myself of such variations andmodifications as come within the scope of the appended claims.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

1. A butter cutter of the class described, comprisin a frame havingoppositely disposed side rails; an outwardly projecting flange on eachof said side rails, said flanges being provided with a plurality ofaligning spaced notches; a pluralityof cutting elements extendingbetween said side rails and engaging in aligning notches; and aswingably mounted locking bar on each of said side rails for lockingsaid cut-ting elements in engagement with said notches, and stretchingsaid cutting elements in taut condition.

2. A butter cutter of the class described, comprising: a frame having apair of op positely disposed side rails; an outwardly projecting flangeon the upper surface of each of said side rails, each of said flangeshaving a plurality of spaced notches formed therein, the respectivenotches in one flange being in alignment with the respective notches inthe other flange; end rails on said frame; projections extendingoutwardly from the ends of said end rails and underlying said flanges,the upper surface of said projections being spaced from the lowersurface of said flanges; a locking bar pivotally connected at one endbetween said flange and said projection; a plurality of cutting elementsengaging in aligning notches in aid side rails and extending across saidframe, and engageable bysaid locking bar upon movement of said lockingbar to operative position, said cutting elements being irremovable fromsaid frame while in engagement with said locking bar.

3. In a butter cutter of the class described, a cutting elementcomprisinga wire doubled upon itself to provide a U-shaped structure ateach end, said U-shaped structure being angularly, outwardly turned, andagain angularly turned to provide a further U-shaped structure. I

In testimony whereof I have signed the foregoing specification.
